Abstract

The phase windings of a small AC generator are formed in two sections (2a,2b), one displaced one pole pitch from the other. These two winding sections are placed on a coil insertion machine and fitted into the slots in the stator core (1). A similar sequence is followed for the second and third phases, except that these are displaced to give the required phase angle relationships. The windings are preferably wave sindings formed by a continuous conductor in each section of each phase.

Description

3상 교류발전기용 고정자의 권선방법Winding method of stator for three phase alternator

제1도는 본원 발명에 의한 분할파형 권선방법을 설명하기 위한 개략도.1 is a schematic diagram for explaining a divided waveform winding method according to the present invention.

제2도는 1상에 대응하며, 제1도에 도시된 방법에 의해 권선된 코일을 나타내는 사시도.FIG. 2 is a perspective view showing a coil wound in a manner corresponding to one phase and wound by the method shown in FIG.

제3도는 제2도의 A-A선 단면도.3 is a cross-sectional view taken along the line A-A of FIG.

제4도는 본원 발명에 의한 분할 집중 다층 권선법을 설명하기 위한 사시도.4 is a perspective view for explaining the divided concentration multilayer winding method according to the present invention.

본원 발명은 일반적으로 교류발전기 고정자의 권선방법에 관한 것이다. 일반적으로 차량이 더욱 소형 경량화되고 안락한 운행을 하게 됨에 따라, 3상 교류발전기는 더욱 소형 경량화되고, 고출력을 발생하기에 이르렀다. 이러한 경향은 고정자의 홈안에 끼워 맞추어지며 코일의 고충전률을 요하게 되고 생산비를 절감하기 위해 권선시간을 단축시킬 필요가 생겼다. 코일 삽입지그에 의해 고정자홈에 소정의 권선수를 가진 하나의 코일을 삽입하는 집중 권선방법이 3상 교류발전기 고정자의 권선방법의 한가지로 알려져 있다. 이러한 종류의 권선방법은 예를들면, 1975년 5월16일, 일본특개소 제 55804/1975호(발명의 명칭 : "회전전기기계의 고정자 및 그 코일권선방법")에 기재되어 있다. 그러나 이러한 권선방법은 충분히 고충전률을 제공하지는 못한다.The present invention relates generally to a winding method of an alternator stator. In general, as a vehicle becomes smaller and lighter and more comfortable to operate, a three-phase alternator has become smaller and lighter and generates high power. This tendency is to fit in the grooves of the stator, which requires a high charge rate of the coil and shortens the winding time to reduce production costs. The concentrated winding method of inserting one coil having a predetermined number of turns into a stator groove by a coil insertion jig is known as one of winding methods of a three-phase alternator stator. A winding method of this kind is described, for example, on May 16, 1975, in Japanese Patent Laid-Open No. 55804/1975 (name of the invention: "Stator of a Rotating Electric Machine and Its Coil Winding Method"). However, this winding method does not provide a sufficiently high charge rate.

1981년 10월24일, 일본특개소 제 13161/1981호(발명의 명칭 : "3상 교류발전기 고정자의 권선방법")에 분할 권선방법이 기재되어 있다. 코일의 고충전률을 제공하지만, 이러한 방법은 권선을 행할때, 고정자홈의 엇갈림배열에 분할코일을 하나씩 삽입하는 단계로 구성되어 있어 권선시간이 오래 걸린다.On October 24, 1981, Japanese Patent Application Laid-Open No. 13161/1981 (name of the invention: "winding method of stator of three-phase alternator") describes a divided winding method. While providing a high charge rate of the coil, this method consists of inserting split coils one by one into a staggered array of stator grooves when winding, which takes a long winding time.

1975년 4월25일, 독일특개 제 2348641호(발명의 명칭 : " 전기기계 또는 장치의 권선방법")에는 그 도면의 제7도에 분할 파형다층권선에 대해 나타내고 있지만, 이는 어쨋든 명백히 권선방법을 설명하고 있는 것은 아니다.German Patent Publication No. 2348641 (Invention: "Method of Winding Electrical Machines or Devices"), on April 25, 1975, shows a divided corrugated multilayer winding in FIG. 7 of the figure. It is not explaining.

그러므로 본원 발명은 고코일충전률을 제공하며, 권선시간을 단축시킬 수 있는 3상 교류발전기 고정자의 권선방법을 제공하는데 있다.Therefore, the present invention is to provide a winding method of a three-phase alternator stator that can provide a high coil charge rate, and can shorten the winding time.

본원 발명은 고정자코일을 분할해서 소정 피치씩 이 분할코일을 엇갈리게 하고, 사전에 코일삽입지그에 이들 코일을 끼워 맞추는 동시에 코일삽입지그와 함께 고정자홈안에 이들 코일을 삽입시킨다.The present invention divides the stator coils, staggers the split coils by a predetermined pitch, fits these coils in advance into the coil insertion jig, and simultaneously inserts these coils into the stator groove together with the coil insertion jig.

제1a도에 있어서, 교류발전기 고정자의 1상에 대응하는 파형권선(2a)는 권선피치(P)에 의해 치형상으로 성형되어 있다. 이 도면에는 도시되어 있지 않지만, 파형권선(2a)과 동일한 형상 및 피치를 가진 파형권선(2b)도 형성된다.In FIG. 1A, the waveform winding 2a corresponding to one phase of the alternator stator is formed into a tooth shape by the winding pitch P. As shown in FIG. Although not shown in this figure, a waveform winding 2b having the same shape and pitch as the waveform winding 2a is also formed.

제1b도에 있어서, 파형권선(2a)은 이 도면에 도시된 바와같이, 코일삽입지그의 안내봉(3)에 끼워 맞추어진다.In FIG. 1B, the corrugated winding 2a is fitted to the guide rod 3 of the coil insertion jig, as shown in this figure.

제1d도에 있어서, 파형권선(2d)은 코일피치(P)의 거리만큼 파형권선(2a)에 대해 엇갈리게 코일삽입지그의 안내봉(3)에 끼워 맞추어진다.In FIG. 1d, the corrugated winding 2d is fitted to the guide rod 3 of the coil insertion jig staggered with respect to the corrugated winding 2a by the distance of the coil pitch P. In FIG.

제1c도에 있어서, 고정자(1) 및 고정자(1)의 홈이 성형 도시되어 있다. 제1d도에 도시된 파형권선 (2a), (2b)는 동시에 공지방법에 의해 제1c도에 도시된 홈(f)안으로 삽입된다.In Fig. 1c, the stator 1 and the grooves of the stator 1 are shown molded. The corrugated windings 2a and 2b shown in FIG. 1D are simultaneously inserted into the grooves f shown in FIG. 1C by a known method.

제2도 및 제3도에 있어서, 1상에 대응하는 파형다층권선의 파형권선(2a), (2b)은 고정자홈(f)에 각각 삽입 되어 있다.2 and 3, the corrugated windings 2a and 2b of the corrugated multilayer winding corresponding to one phase are inserted into the stator groove f, respectively.

제1도 내지 제3도는 교류발전기 고정자의 1상에 대응하는 파형권선법을 도시하고 있다. 3상권선은 예를들면 제1도의 방법에 의해 V및 W상의 권선을 감아서 권선으로 형성할 수 있으나 이들 권선은 두개의 홈에 의해 서로 엇갈려 있다.1 to 3 show the waveform winding method corresponding to one phase of the alternator stator. The three-phase winding can be wound into windings of the V and W phases, for example, by the method of FIG. 1, but these windings are staggered from each other by two grooves.

제1b도 및 제1d도는 각 파형권선((2a), (2b)이 코일삽입 지그의 안내봉(3)상에 감겨 있는 경우를 나타내고 있지만, 본원 발명은 특히 여기에 제한되어 있는 것은 아니다. 예를들면, 코일삽입지그의 축방향에 따라 제1b도 및 제1d도에 도시한 바와같이, 권선(2a), (2b)이 끼워 맞추어져 있지 않은 위치에 각 권선((2a), (2b)을 삽입할 수 있으며, 고정자홈(f)안에 이들 권선을 끼워 맞출 수 있는 것이다.1B and 1D show a case where each of the corrugated windings 2a and 2b is wound on the guide rod 3 of the coil insertion jig, but the present invention is not particularly limited thereto. For example, as shown in FIGS. 1b and 1d along the axial direction of the coil insertion jig, the respective windings 2a and 2b are positioned at positions where the windings 2a and 2b are not fitted. Can be inserted, and these windings can be fitted in the stator groove (f).

제4도는 코일삽입지그의 안내봉(3)에 대해 교류발전기 고정자의 1상에 대응하는 집중권선(2a)을 끼워맞추는 방법을 나타낸다. 또 제4도의 분할집중 다층권선의 집중권선(2a), (2b)은 제1a도 내지 제1d도에 도시된 방법에 의해 고정자홈(f)안에 삽입할 수 있다.4 shows a method of fitting the concentrated winding 2a corresponding to one phase of the alternator stator to the guide rod 3 of the coil insertion jig. In addition, the concentrated windings 2a and 2b of the divided concentrated multi-layer winding of FIG. 4 can be inserted into the stator groove f by the method shown in FIGS. 1A to 1D.

또 제4도에 도시된 분할집중 다층권선은 상기 분할파형 다층권선과 같은 방법으로 다상 다층 구성으로 할 수 있다.The divided concentrated multilayer windings shown in FIG. 4 can have a multiphase multilayer configuration in the same manner as the divided waveform multilayer windings.

본원 발명은 상기 방법으로 분할권선구조를 구성할 수 있으므로 분할 권선구조를 적용하지 않는 종래의 코일의 폭에 비교할 때, 제2도에 도시된 코일(2a) 또는 (2b)의 폭 (t2))을 축소시킬 수 있다. 그러므로 각 상의 코일의 겹쳐진 위치를 축소시킬 수 있으며, 따라서 코일충전률은 매우 향상될 수 있다. 더우기 본원 발명의 방법은 소정권선수로 임의로 분할하고, 코일피치(P)에 따라 코일을 분배하며, 이들 코일을 사전에 그리고 순차적으로 코일삽입지그(3)에 끼워 맞추며, 동시에 상기 코일삽입지그(3)에 의해 대응 고정자의 홈(5)안으로 이들 코일을 끼워 맞추는 것으로 이루어진다. 그러므로 본원 발명의 방법에 의하면 권선시간을 매우 단축시킬 수 있다.In the present invention, since the divided winding structure can be configured by the above method, the width t 2 of the coil 2a or 2b shown in FIG. 2 is compared with the width of the conventional coil which does not apply the divided winding structure. ) Can be reduced. Therefore, the overlapping position of the coils of each phase can be reduced, and thus the coil filling rate can be greatly improved. Furthermore, the method of the present invention arbitrarily divides into predetermined windings, distributes the coils according to the coil pitch P, fits these coils to the coil insertion jig 3 in advance and sequentially, and simultaneously the coil insertion jig ( 3) fitting these coils into the groove 5 of the corresponding stator. Therefore, according to the method of the present invention, the winding time can be shortened very much.
